Image Number 4 for United States Patent #8155087.

The mobile station performs Fourier transform of a signal received from a base station presently in communication in parallel to demodulation processing, by means of a plurality of FFT each having FFT start timing shifted one after another, so as to detect the synchronous timing of another base station by detecting correlation through a pattern comparison with a subcarrier signal including the pilot signal of the other base station.
